6 Claims. (Cl. 15-75) This invention relates to eating and drinking utensil washing apparatus and more particularly to apparatus for washing and cleansing glassware, silverware and dishes.

The present invention provides apparatus conveniently and compactly arranged in a unit in which waste maten'al may be removed from eating utensils and disposed of, in which silverware may be soaked, in which glassware may be washed and in which dishes may be washed and rinsed.

This invention provides drinking glass washing apparatus wherein the inner and outer surfaces and the edge of glasses are Washed and cleaned by brushes and in which the brushes, when not in use after the cleaning operation, are permitted to dry thereby prolonging the life thereof.

The present invention provides a machine comprising a rectangular-shaped frame, the opposite sides of the frame being of greater length than the opposite ends thereof. A rectangular-shaped, liquid-tight tank is supported in the frame and comprises opposite side members attached to opposite sides of the frame, opposite end members attached to opposite ends of the frame and extending transversely thereof and a bottom extending in a horizontal plane intermediate the top and bottom of the frame and between the opposite side and end members, the opposite side members and end members being in liquid-tight relationship with one another and the bottom beng in liquid-tight relationship with the opposite side and end members. The tank is divided into a plurality of conveniently and compactly arranged compartments separated from one another in a liquid-tight manner. A rectangular-shaped prewash and garbage disposal compartment extends transversely of the tank at the forward end thereof while a rectangular-shaped silverware soaking compartment having a removable tray therein in which silverware is placed which compartment is of a width somewhat less than the width of the tank extends along one side of the frame longitudinally thereof from the prewash and garbage disposal compartment to a dishwashing compartment at the opposite or rearward end of the machine. The dishwashing compartment has revoluble wash water and revoluble rinse water arms by means of which wash water and rinse Water is provided for washing and rinsing the dishes, the compartment being covered by segmentally-shaped hoods during the washing and rinsing operations. Disposed laterally of the silverware soakingI compartment and also v Each of the containers has a rotatable inner brush which engages the inner surface of the glass and a rotatable outer brush which engages the outer surface of the glass ,andwhich washes and cleans the glass as it is held stationt ary. The containers have liquid outlets below the level of the brushes so that water will drain therefrom after the washing operation so that the brushes will thereafter dry. Wash water is recirculated from the glasswashing compartment into the glass containers while water from the dishwashing compartment, silverware soaking compartment, glasswashing compartment and prewash and garbage disposal compartment may be drained therefrom through a common drain after the cleaning and washing operations are completed. Water for the silverware soaking compartment, glasswashing compartment and prewashing compartment is supplied through a pivoting spigot. A track by means of which a tray of dishes to be washed is conducted from the forward end of the machine to the dishwashing compartment at the opposite end thereof is provided and extends along the top of the machine.

The invention will be understood from the following description when considered in connection with the accompanying drawings forming a part thereof and in which:

Fig. 1 is a side elevational view of the apparatus of the present invention with parts thereof broken away;

Fig. 2 is a plan view of the apparatus shown in Fig. 1, and

Fig. 3 is a vertical view taken on the line 3 3 of Fig. 2 but on an enlarged scale.

Like characters of reference refer to like parts throughout the several views.

Referring to the drawings, particularly Figs. 1 and 2, the reference numeral 10 designates the frame of the utensil cleaning and washing apparatus of the present invention which is rectangular-shaped and comprises opposite side members 11 and 12, opposite end members 13 and 14 and a bottom 15. The opposite sides and ends are so joined as to form a liquid-tight, rectangular tank or chamber 16. Tank 16 is supported at its four corners on vertically extending legs 17 which project below the bottom 15. A table top is formed on the top of frame 10 by llanges 18, 19, 20 and 21 which extend outwardly at right angles from opposite side members 11 and 12 and opposite end members 13 and 14 respectively.

Tank or chamber 16 is divided into a plurality of compartments separated from one another in a liquid-tight manner. A rectangular-shaped prewash and garbage disposal compartment 22 is formed at one end of tank 16 by positioning a partition 23 so that it extends transversely of the tank in spaced relationship with end member 13 between side members 11 and 12 against which the opposite ends of the partition abut in a liquid-tight manner. The upper side edge of partition 23 is at a level substantially Hush with the upper surfaces of the anges of the table top while the lower side edge of the partition abuts in a liquid-tight manner against the bottom 15 of tank 16. A removable garbage strainer box 24 of a length, width and depth slightly less than the length, width and depth of compartment 22 is positioned in said compartment.

A silver soaking compartment 25 and a glasswashing compartment 26 are formed in the central portion of tank 16 adjacent to compartment 22. Compartments 2S and 26 are also rectangular in shape and extend longitudinally of tank 16, the compartments being disposed laterally. of one another. Partition 23 forms one end of the compartments 25 and 26 while a substantially inverted U- shaped partition 27 longitudinally spaced laterally from partition 23 forms the opposite end of said compartment. The legs 28 and 29 of partition 27 extend transversely of tank 16, the opposite end edges of legs 28 and 29 abutting opposite sides 11 and 12 of tank 16 in a liquid-tight manner while the lowermost edges of legs 28 and 29 abut against the bottom 15 of the tank in a liquid-tight AMII-C relationship. The joining portion 30 of the uppermost edges of the legs is ush withthe top of the table. A longitudinally extending partition 31 separates compartments 25 and 26 from one another, one end edge of par tition 31 abutting partition 23 and the opposite end edge thereof abutting leg 28 of partition 27 in liquid-tight relationship. The lower edge of partition 31 abuts the bottom in a liquid-tight manner while the uppermost edge is substantially flush with the top of the table of -the apparatus. The opposite ends of compartments and 26 are, therefore, formedV by partition 23 and leg 28 of partition 27 while longitudinal partition 31 forms'one side of both of said compartments. The opposite side of compartment 25 is formed by the side 11 oftank 16 and the opposite side of compartment 26 is formed by side`1-2 of said tank. y

Silversoaking compartment 25 has a mesh tray 25' of a dimension slightly less than that of the compartment so that the tray with silver therein may be readily inserted and removed from the compartment.

Glasswashing compartment 26 has glasswa'shing apparatus therein which apparatus, as shown, comprises two cylindrically-shaped glass containers 32 and 33 mounted with the longitudinal axis thereof extending vertically in the compartment. Each of the containers comprises a metallic housing 34 having a top 35 and a bottom 36vclosing opposite Vends thereof. The top has a central opening 37 with a. rubber ring 38 extending there'- around the opening and the ring being of such diameters that a glass may be inserted therethrough to project into vthe containers and the rubber ring will engage the outer surface of the glass to prevent rotation thereof. Each through a pulley 62 on the last-mentioned shaft and a drive belt 60 engaging said pulleys 61 and 62.

A dishwashing machine compartment 63 is formed by the leg 29 of partition 27 at one end thereof and end member 14 of tank 16 at the opposite end thereof and by opposite side members 11 and 12 of said tank. The dishwashing compartment, as shown, has dishwashing and dish rinsing apparatus therein of a well-known type which comprises a rotatable or revolving dishwashing arm 64 extending in a horizontal plane which has a plurality of spaced water outlets 65 that project Water outwardly and upwardly therefrom causing the arm to revolve and the water to be sprayed against the dishes thereabove the water thereafter passing into compartment 63. Water is pumped into the arm 64 by a circulating pump, not shown, which pump circulates Water from compartment 63 into arm 64. After washing the dishes, the pump is stopped by actuation of control lever 66 which stops the revolving of arm 64. Thereafter, the dishes are rinsed by operating control lever '67 which actuates a valve, not shown, permitting rinsing water to 'enter upper and lower rinsing arms 68 and 69 and causing l them to revolve by the emission of water therefrom through outlets 7l) which project the water toward and onto the dishes. During the washing and rinsing operations, the segmentally shaped hood members 71 and 72 are in closed position as shown in dotted lines in Fig. 1. Water is `conducted to rinsing arms 68 and 69 -through pipe 68 having a valve, not shown, therein controlled by lever 67 which pipe 68 is connected to a source of water. Dishwashing compartment 63 is connected by a connection, not shown, to a source of dishwashing water.

of the containers is secured in position in compartment 26 by a mounting 39 which fastens the bottoms 36 of the containers to bottom 15 of the tank 16. Mountingsv 39 have a longitudinal bore therein the center of which is in substantial vertical alignment with the center of opening 37 and ring 38. Vertical shafts 40 are rotatably mounted in mountings 39 and extend vertically upwardly into containers 32 and 33 and downwardly below bottom 15 of tank 16. Suitable packing 41 and 42 is used to prevent leaking of liquid around shafts 40. An inner brush 43 which is of such diameter that the bristles 44 thereof will bear against the inner surface of a glass insertedV through openings 37 into containers 32 and 33 is mounted on shafts so as to rotate therewith while a circular outer brush 45 comprising a cylindrical upright 45 mounted on a spoked tting 46 whi'ch'is fastened to shafts 40 to -turn therewith has bristles 47 which pro ject outwardly from upright 45 a sufcient distance to bear vagainst theouter 'surface of a glass inserted through opening 37. The bristles of the brushes 43 and 45 extend outwardly of their lmounting from a point adjacent the tops of the containers to a point in spaced relationship with'thebottoms 36 of containers' 32 andV 33. Water for washing glasses in containers 32 and 33 'is circulated fromV compartment 26 by a pump 48 which has a suction in communication with compartment 26 through an 'out- `let 49 in compartment 26 and a suction pipe v50 andha's its Youtletv in communication with the interior of containers 32 and 33 through pipe 51 and branch pipes 52 and 53. Water from the containers 32 and 33 drains into compartment `26 through openings 54 while, after the washing operation, water drains from said compartment through a drain outlet which has an opening at alevel below the level to which the brushes 43 and 45 extend, the openings 54-being at this level also. The pump 48 is driven by electric motor 56 which motor also drives shafts 40 through a belt 57 engaging drive pulley 53 on the motor shaft and sheave 59 on one of the shafts 40, sheave 59 being of substantially greater diameter than pulley 58 so that the speed of rotation of shaft 40 will be less than that of the motor shaft. A pulley 61l on the first-mentioned shaft 40 drives the other :shaft 40 L-shaped track members 73 and 74, Fig. 2, extend longitudinally of tank 16 at the top thereof, the member V"73 being adjacent to side member 11 while the track member 74 is adjacent side 12. The track members are provided so that a tray of dishes may be slid thereon i' from the end 13 of the apparatus longitudinally thereof to the dishwashing compartment after the washing and rinsing operations, hood segment 71 is raised andv the tray of dishes is removed at the end of the apparatus adjacent end member 14.

`A drain pipe 75 is in communication with prewash compartment 22 through drain outlet 76, with silver `soaking compartment 25 through drain outlet 77, with glasswashing compartment 26 through drain outlet 55 and with dishwashing compartment 63 through drain outlet 78.

Water for compartments 22, 25 and 26 is supplied through pivoting spigot 79 which receives water from taps 80 and 81.

In operation, prior to cleaning eating and drinking utensils in the apparatus of the present invention, valve 82 in drain pipe 75 is closed so that water'will not ow through the drain pipe and will, therefore, be retained in'compartm'ents 22, 25, 26 and 63. Water for'washing the glasses is provided to compartment 26 by turning the spigot 79 so that water therefrom runs into said cornpartment while water for soaking silver is provided by turning spigot 79 so that water therefrom will run into compartment 25. Control levers 66 and 67 are set so that water'will not run into rinsing Varms 63 and 69 and Washing armY 64. Hood segment 71 is set in its open position las shown in Figs. 1 and 2. The silverware soaking compartment 25 and the glass washing compartment 2.6V are then lled with wash water, the normal level of the water in compartment 26 being somewhat below'the level of the tops 35 of containers 32. Waste matter is scraped from the dishes to be washed over prew'ash and garbage disposal compartment 22, water from spigot 79 Abeing used toV assist removal of said 'iwast'eQ T-hefdishes are then placed in a tray or basket of any well-known type which tray or basket is placed on track members 73 and 7 4 and, When the tray is tilled with dishesf to be washed and rinsed, is slid on the track members into-a positionunder the-segmental hood'n'lemw bers 71`and.72" and over A'dishwashing compartmentv.`4`r Hood memberjlis then moved in a clockwise direction fromL its opent position,1as shownfin ful-l linesin Fig. 1, l intoiits-closed-position as indicated by Vdotted lines in'y 5 Fig. 1.
